Filling the pit and finalizing the surroundings
1. If required for local frost conditions, add insulation around the column foundation.
2. To minimize the growth of grass, use geotextile below the foundation and below the
service platform around the MVCS. Put the geotextile 20 cm (8 in) below and about 100
cm (40 in) around the foundation.
3. The MVCS is a not walking station, it is designed to be operated from the outside.
Provide a permanent or portable platform for comfortable operation of the MVCS
switching devices as the foundation can be higher than the surrounding ground. For
platform design and construction, follow the local rules and standards.
4. Do not plant trees near the MVCS. If bushes are planted, make sure that the planting
compost base is at least one meter (40 in) away from the station housing and that the
fully-grown bushes do not prevent maintenance access to the MVCS. Make sure that
anything planted near the inverter does not discharge dust or seeds that can affect the
cooling air flow.
